6.6.2. Clean (Wash) Switches
Some refrigerated cases may be outfitted
with clean switches (also called "wash
switches") that disable all case systems so that
they may be cleaned or serviced. The CUB-II
will respond to a contact closure of a clean
switch by locking the compressor, defrost, and
case fans OFF for as long as the switch is active.
The CUB-II may be programmed with a fail-
safe time to prevent the case from being in clean
mode for too long. If this fail-safe time is passed,
the CUB-II will resume normal control regard-
less of the position of the clean switch.
